.T0 @ZZ whom t may concern,.-

Be it known that I, JACOB BURMANN, of Bienne, Switzerland, have inventeda new and Improved Watch-Stand and Electrical Alarm- Watch, (which hasreceived Letters Patent protection in France, February 25, 1885, No.165,089, and in Italy February 1S, 1885,) of which the following is afull, clear, and exact description.

The object of my invention is to provide a new and improved watch-standcontaining an electric-bell, which is sounded when the circuit is closedby an ordinary watch having` circuit closing devices and placed on thestand.

The invention consists in the construction and combination of parts anddetails, as will be fully set forth and described hereinafter.

Reference is to be had tothe accompanying drawings, forming part of thisspecification, in which similar letters of reference indicatecorresponding` parts in all the iigures.

Figure lis a longitudinal sectional elevation of my improved electricalarm-watch stand. Fig. 2 is a front View of the same. Fig. 3 is anenlarged face view of the watch. Fig. 4 is an enlarged cross-sectionalelevation of the same.

In a wooden boX, A, the electric batteryB, of any desired wellknownconstruction, is placed, and in the top ofthe boX a metal arm, E, isfastened, on which a bell or gong, C, is held by means ol' the screw J.

The bell covers the ala rm mcchanisni,wliich consists of anelectromagnet, l), having an armature, G, carrying a hammer, M, forstriking the bell C.

A metal piece, L,'held by the screw J, has the arms Z, Z, 'and Z, whichserve to hold the watch D, the arm Z having its end forked, and the armsZ r having hooks. rllhe arm Z is hinged so that it can be swung down, asshown in dotted lines in Fig. I, when the apparatus isl to be packed.The screw J establishes a metallic contact between the piece L and thearm E on the bell, which arm E and bell C are insulated by two pieces,K, of insulating material.

A metal spring, Y, is held between the insulating-pieces l, and itsinner end rests upon the upper end of a wire, X, surrounded by a tube,YV, of insulating material, thelower end of the wire X resting on aspring, II, with which it is brought in electrical contact. The springis connected with one pole of the battery B.

The arm E, on which the stud G is fastened, bearing the Vibratingarmature G', is in elecn trical contact with the stud F by means of thespring G.

rl"he stud F is insulated from the arm E, and connected with one end ofthe coil of the magnet, the other end of which coil is connected withthe switch N O l), or directly with the battery B.

If the alarm is to be used, the puslrpin P must be pushed inward tobring the parts N and O of the switch in contact, the pin P being lockedin place by the spring Q.

It is evident that an alarm will be sounded as soon as an electriccontact is established between the spring Y and one of the arms Z, Z, orZ.

A ring, I', of insulating material is held between the case D and thebezel A, which bezel is provided with an adjustablemetal hand orpointer, C', which can touch the hour-hand Bl of the watch, the saidpointer C being below the crystal held in the bezel. A small platinumspring or contact-piece` B, is held on the end of the hour-hand B, or onthe pointer C', which spring` or contact-piece may have a greater orless width, according to the time the circuit is to remain closed.

The pointer G is then placed to the hour, &c., at which the alarm is tobe sounded, and when the hour-hand arrives at the said pointer thecircuit will be as follows: From the battery through the spring Y, thebezel A', the hand C', the hand B', through the metallic parts of thewatch, the arms Z Z Z, and through the electro magnet to the battery,when the hammer M is operated and the alarm sounded.

The box may be provided with the pushbutton U and the springs B T, bymeans of which the circuit can be closed at any time by pushing thebutton U inward to give an alarm or signal, thus adapting the stand tobe used as a call-bell.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A Watch-stand having devices, substantially asdescribed, for holding removably an ordinary pocket Watch, andcontaining an electric alarm electrically connected to the Watch-holdingdevices, and an electric closingcircuit,substantially as and for thepurpose set forth.

2. The combination, with a watchstand, of an electric bell on the same,arms for holding` the Watch connected with 'the alarm mechanism, and ofa spring connected With the alarm mechanism, and which can be brought inContact with the bezelof thewatch, substantially as herein shown anddescribed.

3. Thecombination, with a Watch-stand for holding an orinarypocket-Watch, of an electric bell, arms for holding the said Watchreniovably and connecting electrically with the bell mechanism, and withan electric circuit closing device for sounding thelbell when de sired,substantially as herein shown and de- 25 scribed.

4. The combination, with a Watch stand containing an electric bell, ofarms 'for holding the Watch,wl1ich arms are in electrical contact withthe bell mechanism, a spring which 3o can rest against the bezel of thewatch, and of an adjustable contact-piece on the bezel, substantially asherein shown and described.

5. The, combination, with a Watch-standfor holdinga pocket-Watchremovably, of an elec- 3 5 tric-bell mechanism connected Withthewatchholding arms of said stand, and of a switch for breakingtliecircuit, substantially as herein shown and described, and for thepurpose of putting tliebell mechanism out of operation. 4o

6. A Watch having its bezel insulated from the case, and an adjustablehand on said bezel7 substantially as herein shown and described.
